Nucleons and higher spin baryon resonances: an AdS/QCD configurational entropic incursion

preprint2020arXivOpen access

Abstract

Families of JP=1/2+J^P=1/2+ nucleons (N(939), N(1440), N(1710), N(1880), N(2100), N(2300)) and JP=3/2−J^P=3/2- nucleons (N(1520), N(1700), N(1875) and N(2120)) are scrutinized from the point of view of the configurational entropy (CE). The mass spectra of higher JPJ^P resonances in each one of these families are then obtained when configurational-entropic Regge trajectories, that relate the CE of nucleon families to both their JPJ^P spin and also to their experimental mass spectra, are interpolated. The mass spectra of the next generation of nucleon resonances are then compared to already established baryonic states in PDG. Besides the zero temperature case, the finite temperature analysis is also implemented.
